The last statement is incorrect.
The clear'ness of the property can be found with the builtin function:
  is_clear_property(OBJ, "property")
And you can make a property clear with the builtin function:
  clear_property(OBJ, "property")
When a property is 'clear', the value of that property on the object's
parent is shown.
